Patent CA-2392210-A1 (CA)
Title: Degradable cross-linking agents and cross-linked network polymers formed therewith
Inventor: THOMAS ALLEN A
IPC: A61L24/00
Filed: 2000-06-22
Abstract: Degradable cross-linkers which are used to form polymer networks which degrade under aqueous conditions are described. These cross-linkers comprise a monodispersed central polyacid, monodispersed monomeric or monodispersed oligomeric degradable regions and an optional water soluble regions. These monomers are preferably polymerized using free radical or condensation polymerization. Degradation occurs at degradable regions such as ester linkages after cross-linking polymer filaments, and results in soluble polymer filaments which may be cleared from the body. Preferred applications of these materials include, for example, controlled release of drugs and cosmetics, tissue engineering, wound healing, hazardous waste remediation, metal chelation, swellable devices for absorbing liquids and the prevention of surgical adhesions.
